Abstract

A continuously variable belt-drive transmission for a motor vehicle with two pairs of conical discs (11, 21) has a compact layout arrangement where the torque flows from a prime mover through an input shaft (2), start-up element (4), torque sensor (10), first conical-disc pair (11), chain-belt (25), second conical-disc pair (21), direction-reversing element (28), and output shaft (3) to the wheels of the vehicle.
